To all fio/tom t may concern Be it lnown that l, lRviNe SONNENTHAL, acitizen of Foland, and a resident of New York city, borough or"Manhattan, in the county and State of New York, have invented certainnew and useful lmprovements in Hoolr-Latclies, or" which the followingis a full, clear, and exa-ct description.

imong the principal objects which the present invention has in view are:to pravent the accidental releasing of a -latch of the charactermentioned; to afford a neat and worlnnanlile appearance; to strengthenthe construction; and to simplify and cheapen the construction.

Drawings.

Figure 1 is a longitudinal view of a latch constructed and arranged inaccordance with the present invention, the latch being shown inconjunction with the end` fragments oit a silk Wristband, and in theopen position;

Fig. 2 is a similar view showing the device in its closed position;

Fig. 3 is a side view oi' the device showing the parts as in the openposition;

Description.

The latch herein disclosed is particularly adapted tor use withwristbands constructed of ribbon, or other flexible material. To thisend one extremity of the ribbon Vl0 is permanently attached to a metalloop 11, the forward bar of which engages a service hooi-r 12. The ser'ice hook 12 is slidably mounted within shield hoolr 13, formedintegrally with a buckle body 14- the extremity ot said hoolz beingdisposedlin parallel relation to the buckle body 14. As seen best inFig. 4f ot the drawings, the body lll has by design a series of gridbars 15, about and through which the looped end of the other extremityof the ribbon 10 is woven.

The shield hook 13 forms a guide for the hook l2 during the movement otthe hook 12 lengthwise o'f the shield hook 13. In the normal position ofthe hook 12, as seen in Figs. 2 and 5 of the drawings, the extremity otthe shield hook 13 serves as a guide for a hollow hood 16, within thehollow of which said shield hook enters and is housed.

Cooperating with the vshield hook 13, to maintain the normal servicerelation of the hook 12, is a tongue that extends through a slot formedin the overturned bracket 18. he bracket 18 is integral with the body14, and with the shield hook 13, being preferably cut or punched from asingle plate or sheet of metal.

In operation the hood 16 is drawn back to uncover the end of the shieldVhook 13. ln this operation the tongue 17 is extended through the slot19, in which it rests, and the extremity of the hook 12 is drawn forwardto approximately aline with the eX- tremity ot the hook 13, as shown inFigs. 1 and 3 of the drawings. As the loop 1l has been disposed withinthe hook 12, it may now be removed therefrom, when the hood 16 and partsassociated therewith are again moved forward, until the said hoodengages the extremity of the shield hook 13. By this larrangenient themovable part, constituted by the hood 16, the hook l2, and tongue 17, isprevented from disarrangement or separation from the body 14 and partsassociated therewith. When it is desired to again place the loop l1, orsome other loop within the hook 12, the hood 16 is drawn back to theposition shown in Fig. 3, to admit the said loop, which then is employedto draw the hook 12 and parts associated therewith into the normal orclosed position.

The latch may be used in many services. One service for which it isparticularly fitted is i'or use on a bracelet for wrist watches. lt willbe observed that the normal tendency oit the hood 16 and partsassociated therewith is to assume the position where the latch isclosed, and Jfrom which it is difficult to remove by accident the loop11.
